Abstract
Full-bodied materialism is a rarity in British philosophy. In fact, notable British materialists before recent times seem to number only two: Thomas Hobbes in the seventeenth century, and Joseph Priestley in the eighteenth. Their materialisms were attempts to construct a scientific ontology, but there the similarity ends, since they had very different ideas of the nature of science. Hobbes took science to be the study of motion, using Galilean geometric method; Priestley worked with a Newtonian methodology and conceived of matter as spheres of force centred on point particles.
